laea e To all whom it may concern V Be it known that I,JoHN M. MURPHY, a citizen of the United States of America, and resident of Shamokin, in the county of N orthumberland and State of Pennsylvania, have invented certain new and useful Improvements in Pipe Carriers for Signaling Systems, of which the following is a specification. 1

This invention relates to signal operating guiding mechanism, the said invention having for its object the provision of novel means for supporting signal operating rods or pipes which are employed to enable the switch or signal to be operated at a distance, as is now commonly done along railway tracks, there being a plurality of supporting members or brackets in spaced relation to each other extending along the track, in order that the switch operating pipe may be supported to have reciprocatory motion. I

During the description, the element which is moved for the purpose of actuating the switch will be termed a pipe, as that is the form of rigid element which is now most usually employed for communicating the motion of a switch operating lever to the switch or to a signal carrying bracket.

An object of this invention is to provide a pipe supporting and carrying device l1av ing novel means for minimizing the friction, and having means also which will prevent'the parts from becoming rusted to a degree that they will prove inoperative, it being the purpose of the invention to provide a bearing for a supporting roller, the trunnion of which-is looselyapplied to its support in order that the said trunnion may not rust and become inoperative. A still further object of this invention i to provide side guides or elements for engaging the sides and top of the pipe to prevent its dislodgment from the supporting roller; the said invention furthermore contemplating the production of a support of the character indicated which will wear evenly and which will not readily be impaired by use; the said invention further contemplating an arrangement of parts by which the lateral guiding members are free to rotate and are not restricted in their movement by any superimposed structure.

With the foregoing and other objects in view, the invention consists in the details Specification of Letters Patent.

of construction, and in the arrangement and comblnatlon of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail ref erence will be had to the accompanying drawings forming part of this application wherein like characters denote correspondlng parts in the several views, and in which- Figure l illustrates a sectional view of a pipe, showing it in operative relation to the supporting device;

Figure 2 illustrates a side elevation of one of the said supporting devices;

Figure 3 illustrates a top planview of one of the journal brackets;

Figure 4 illustrates a plan view of a fragment of a tie bar; and

Figure 5 illustrates, a perspective view of a fragment of one of the brackets.

In these drawings, I have illustrated in Figure 1, three brackets employed for retaining two supporting rollers and adapted to operate in conjunction with two pipes. In carrying out the invention, I employ brackets which are practically duplicates of each other. and therefore, a description of one will suflice as a disclosure of them all.

Each bracket has feet 11 and 12 by which it is anchored in place, and each of said brackets has an elongated horizontally disposed bearing 13 with extended flanges let, in order that the trunnions 15 of the supporting rollers 16 may rotate freely in the bearings and travel to some'extent longitudinally of the flanges. The purpose of having the trunnion loosely journaled in order that it will travel with respect to the bearing and flange which it engages, is to insure against corrosion of the trunnion or bearing which might interfere with the rota- .tion of the trunnion. Where devices of this kind are inactive for a length of time and the trunnion closely fitted the bearing, corrosion might occur which would cause an adherence of the trunnion and prevent its rotation; but by this device,,there is no likelihood of a condition arising which would render the supporting roller inoperative. The'trunnions project from shoulders 17 on the sides of the roller and these shoulders act in conjunction with the edges of the flanges as guides, and they prevent the displacement of the rollers and cause the trunnions to maintain an alinement. The rollers concaved. Then the brackets are properly located for supporting a roller, the peripheries at the upper ends of the anti-friction rollers overlie the pipe 23, which rests on a roller 16, and the periphery of one anti-trio tion member so nearly approaches the other as to leave an opening therebetween of less area than the diameter of the pipe, so that the pipe is prevented from chslodging from the roller, but the said pipe may move over the 7 surface of the roller from side to side and engage either one of the anti-friction members which act'as guards to prevent the dislodgment of the pipe from the suppoi uing roller. The bearing flanges project from each side of each bracket, and hence, when they are being set up, the brackets are interchangeable. r

The upper end of each spindle is angular in cross section, as shown at 2-1, and there is a shoulder 25 between the round portion and the angular portion, each of which shoulders serves as a support for a tie bar 26 having an aperture otthe configuration ot' the upper end of the spindle, in order that it will fit thereover and rest on the shoulder, and these tie bars are retained in place by fastenings 27', such as cotter pins. From an inspection of the drawings, it will be apparent that the anti-friction members 21 are free to move axially of the spindle to a limited extent, but this freedom of motion insures proper action and also guards against friction which might interfere with their operation.

- By reason of the construction and arrangement of parts, the roller of this invention will wear evenly on both sides and insure the alining of the pipe to a much better advantage, but also prove more durable and eflicient than known devices. The tie bars in some of the types used at present, interfere with the free rotation of the roller and pre vents it from turning. V V v The trunnion ofjthe roller 16 is guided on the flange by a flange 16 on each side oi the bracket, and each of the last mentioned flanges is in spaced relation to the bearing flange, and they terminate at their ends in spaced relation to an upwardly projecting portion 16 of the bearing flanges to leave space to permit the trunnionsoit the rollers to be removed between the bearing and guide flanges r V having trunnions rotatabl'y mountedin the elongated bearings oi the brackets, spindles projecting upwardly from the brackets, anti- :triction members rotatabiy mounted on the spindles and having concaved sides forming guards for preventingthe' dislodgmentof a r p r l :2. in a carrier for signal pipe lines,- brackets having elongated bearings therein, said brackets being arranged in pairs, a roller having trunnions rotatably mounted in the elongated bearings oi the brackets, spindles projecting upwardly from the brackets, antifriction members rotatably mounted on the spindles and having concaved sides forming guards for preventing the dislodgment oi a pipe, the said spindles having upper ends angular in cross section and a shoulder between the said end and the spindle, a tie bar having apertures contorming 1n contour to the shape of the upper ends of the spmdles and applied thereto, and means for holding the tie bars in place.
